Prevent certain username colors

Greetings, a board I assist in admining uses colored usernames to make it easier to discern between staff and regular members. Some people are buying their username color the same as staff and it is confusing people. Is there any way to disallow the choice of a particular color?

Well, u can set the colors that are usable now.

Manage Options -> Change Username Color -> Input Fields -> Username -> Set the value like this... "Red,Black,Yellow,Orange,etc" to all of the colors that u want ur users to be able to purchase.
